Initial release of Microsoft's first advanced reasoning model, trained from scratch on proprietary data without distillation from other models.
Initial release of MAI-Thinking-1, a 35B parameter reasoning model trained on commercially licensed data without third-party model distillation. Available to select early partners.
Microsoft announced two new language models: MAI-Thinking-1, a 35B parameter reasoning model available to select early partners, and MAI-Code-1-Flash, a 5B parameter coding model rolling out to GitHub Copilot individual users in VS Code. Both models were trained on commercially licensed data without distillation from third-party models.
Microsoft released seven AI models at Build 2026, headlined by MAI-Thinking-1, its first reasoning model with 35 billion parameters. The company claims the model matches Anthropic's Claude Opus 4.6 on SWE Bench Pro coding benchmarks and beats Sonnet 4.61 in blind tests.
Microsoft announced MAI-Thinking-1, its first advanced reasoning AI model, at Build 2026. The company claims it's a medium-sized model matching leading models on key software engineering benchmarks, trained from scratch without distillation from third-party models.
Microsoft will announce MAI-Thinking-1 at its Build conference on June 2, 2026, according to sources cited by The Verge. The model is Microsoft's first reasoning model and was not trained using distillation from other AI models. The company will also reveal MAI-Image-2.5 and MAI-Image-2.5-Flash image models, along with a new developer-optimized Windows 11 experience.
